Technical Field
[0001] This utility model belongs to the technical field of exhaust pipe production equipment, and in particular relates to a cutting device for producing exhaust pipes for yacht engines. Background Technology
[0002] During the manufacturing process of yacht engine exhaust pipes, according to the design drawings, cutting machines, cutting devices, or saws are used to cut the pipes (round pipes, square pipes) or plates into straight pipe sections, flanges, muffler components, etc. Subsequent shaping and welding processes are then carried out to obtain the desired finished exhaust pipe.
[0003] Chinese utility model patent CN215880101U, entitled "A Cutting Device for Automobile Exhaust Pipe Production," discloses the following: A base is included, a support box is fixedly installed on one side of the base, and a clamping device is provided between the top of the base and the support box. A support plate is fixedly installed on the side of the base away from the support box, and an mounting box is fixedly installed on the top of the support plate. An electric telescopic rod is fixedly installed on the inner wall of the top of the mounting box, a driving device is connected to the top side wall of the electric telescopic rod, and the bottom end of the electric telescopic rod passes through the mounting box and is fixedly installed with a protective box. This utility model has a novel structure, and the device can not only clamp and fix exhaust pipes of different sizes, but also improve the stability of the device. Furthermore, the angle of the cutting blade can be adjusted to facilitate cutting different bevels, thus improving the practicality of the device.
[0004] However, this device has the following drawbacks:
[0005] In practical use, manual operation is required to determine the length of the pipe to be cut. The cutting length must be remeasured each time, resulting in low efficiency and increased workload for the operator. During the cutting process, sparks are generated during the friction between the grinding wheel and the pipe. The device lacks protective components, posing a safety hazard during use.
[0006] Therefore, there is an urgent need for a cutting device for the production of yacht engine exhaust pipes to solve the above-mentioned technical problems. Utility Model Content
[0007] The purpose of this invention is to overcome the existing technical problems and provide a cutting device for the production of yacht engine exhaust pipes.
[0008] To achieve the above objectives, this utility model is implemented according to the following technical solution:
[0009] A cutting device for producing exhaust pipes for yacht engines includes an operating table with a liftable cutting assembly, which includes a cutting grinding wheel; multiple support legs are fixedly mounted on the lower end face of the operating table; and a limiting assembly and a pipe clamping assembly are also included.
[0010] A horizontal placement groove is provided in the center of the upper surface of the operating table, and a rectangular cutting notch is provided at the left end of the operating table; the cutting wheel is located on the left side of the upper surface of the operating table, and the vertical downward projection of the cutting wheel falls into the cutting notch; the pipe clamping assembly is located on the right side of the cutting wheel.
[0011] The limiting assembly includes a limiting plate, connecting rod A, connecting rod B, and multiple guide rods;
[0012] A mounting tube is fixedly installed on the front side of the lower end face of the operating table, and the inner diameter of the mounting tube matches the outer diameter of the connecting rod B; a mounting hole is provided on the rear side of the operating table, and the inner diameter of the mounting hole matches the outer diameter of the connecting rod A; the mounting hole and the mounting tube are parallel to each other.
[0013] Connecting rod A extends into the mounting hole, and connecting rod B extends into the mounting tube; the left ends of connecting rod A and connecting rod B are fixedly connected to the limiting plate; connecting rod A and connecting rod B are detachably connected by several guide rods.
[0014] Several threaded holes are arranged from left to right on the operating platform directly below the mounting hole; multiple through holes are fixedly arranged from left to right on the lower end face of the mounting tube, and a threaded sleeve is fixedly installed outside each through hole; connecting rod A is pressed and fixed in the mounting hole by fastening screw A that is threaded to the threaded hole, and connecting rod B is pressed and fixed in the mounting tube by fastening screw B that is threaded to the threaded sleeve.
[0015] In use, the position of the limiting plate is adjusted by moving it left and right according to actual needs, ensuring that the distance (horizontal distance) between the right end face of the limiting plate and the cutting wheel meets the cutting requirements. After the limiting plate is adjusted, fastening screws A and B can be tightened to fix the limiting plate. Then, connecting rods A and B between the limiting plate and the operating table are connected and fixed via guide rods, with the guide rods tilted downwards. The pipe is then placed in the placement groove, with its left end contacting the right side of the limiting plate for positioning. The pipe clamping assembly is then driven to press the pipe onto the placement groove, and the cutting wheel is driven to move downwards to cut the pipe.
[0016] The setting of the limit component can control the length of the cut pipe by the position of the limit plate, avoiding the need for manual length positioning every time, saving manpower and making operation convenient; the limit component is fixed by fastening screws, so the distance between the limit plate and the grinding wheel can be adjusted at will, making it more flexible to use.
[0017] Preferably, the connecting rod A and the connecting rod B are provided with multiple connecting holes from left to right, and the connecting holes of the connecting rod A and the connecting holes of the connecting rod B correspond to each other; the head of the guide rod is provided with a screw head, and the tail of the guide rod is provided with an external thread; the tail of the guide rod passes through the corresponding connecting holes of the connecting rod B and the connecting rod A and is threaded with a nut.
[0018] The spacing between the guide rods should be less than the length of the pipe being cut to prevent the pipe from falling directly between the guide rods. Alternatively, the plate can be directly mounted on the guide rods.
[0019] The guide rod forms an inclined plane for the cut pipe fitting to slide down, allowing it to fall smoothly under its own weight. A collection box or conveyor belt can be installed below the sliding surface to collect or transport the cut pipe fitting. The outer diameter of the screw head needs to be larger than the inner diameter of the connecting rod but smaller than the outer diameter of connecting rod B. This restriction prevents the screw head from obstructing the sliding of the cut pipe fitting.

[0024] Preferably, it also includes a debris collection box; the debris collection box is placed below the cutting notch.
[0025] The debris collection box facilitates the collection of debris generated during the cutting process.
[0026] Preferably, it also includes a transparent protective cover; the transparent protective cover is a rectangular parallelepiped that is open at the top and bottom; semi-circular holes are provided on the left and right sides of the transparent protective cover; and connecting edges are provided at the bottom of the front and rear sides of the transparent protective cover.
[0027] A transparent protective cover is fitted over the cutter assembly and is detachably and securely connected to the worktable via a connecting edge.
[0028] The transparent protective cover prevents sparks or debris from flying during the cutting process, providing protection. The connecting edges can be tightened and fixed to the operating table with screws, allowing for removable installation of the transparent protective cover. The semi-circular hole facilitates the passage of pipe fittings.
[0029] The vertical telescopic component in this invention can be one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
[0030] Components not specified in this invention are all made using conventional methods in the field. Those skilled in the art can select their models and installation methods according to actual usage needs, and clearly understand how to install and control them. They will not be described in detail here.
[0031] This utility model achieves the following beneficial effects:
